Common questions

How do I report incorrect crosswind values?

If you find a value that disagrees with your FCOM/QRH, please email with:

  1. The exact inputs you used (aircraft, weight, CG, runway condition, mode).
  2. The value the app showed.
  3. The value you expected (with FCOM page/section reference if possible).

We validate all data with active line pilots, but corrections are always welcome.

Does the app collect any data?

No. The app makes zero network requests. All settings and your last 20 calculations are stored locally on your device. See our Privacy Policy for the full statement.

Why is the app advisory only?

All values are conservative reference numbers. They are designed to give pilots a quick first pass before consulting the FCOM. They do not replace official Boeing documentation, certified EFB software, or your operator's procedures. See our Terms of Use for full details.

Does it work offline?

Yes, completely. The app needs no internet connection at any time. All calculations run on-device.

Will more modules be added?

Possibly — Weight & Balance, Performance V-speeds, and Fuel Planning are on the roadmap. Apple Watch companion is under consideration.
